Cucumber Beetle Antifeedants: Laboratory Screening of Natural Products

Cucumber beetles are destructive pests of melons in the Midwest both because of their feeding and transmission of bacterial wilt disease. Because an effective antifeedant would be an ideal control measure, more than 350 materials of biological origin have been screened against striped cucumber beetle. Such materials as neem derivatives, neriifolin, -tung, and napthoquinones appear promising and will be tested more extensively
